Question

Find out the number of particles in 5 mole of Methane Gas 92 gram of sodium

Answer 1

Number of particles in methane gas are - 3.11*10^24

Number of particles in sodium are -

2.4*10^24

The number of particles in methane gas will be molecules while sodium will have atoms.

According to Avogadro's number, one mole is known to contain 6.22*10^23 number of particles, which are molecules, atoms etc.

Number of molecules in methane gas and sodium will be calculated according to this.

Number of moles of methane gas - 5 mole

Number of moles of sodium - weight/molecular weight.

Number of moles of sodium - 92/23

Number of moles of sodium - 4

Now, calculating number of particles for methane gas - 6.22*10^23*5

Number of particles in methane gas are - 3.11*10^24

Number of particles in sodium are -

6.22*10^23*4

Number of particles in sodium are -

2.4*10^24

Answer 2

Answer:

Ans: 2.4×10^23 particles
